FLOOR CONSTRUCTION FOR REENIORCED CONCRETE.

Application filed March 10, 1922. SeriaLNo. 542,665.

To all whom it may concem:

Be it known that I, J osnPH So'rY, a citizen of the United States, andresident of New York, in the county of New York and State of New York,have invented certain new and useful Improvements in Floor Constructionsfor Reenforced Concrete, of which the following is a specification.

- This invention relates to reenforced -floor constructions and has forits main object to provide such a construction and system of a buildlngand reinforcing concrete floors.

which will do away with the horizontal beams used at present to carrypart of the load on the floor construction.

Another object of this invention is to provide such a system which willmake the top and lower surfaces of the floor. construction perfectlyhorizontal and parallel to each other and thereby make the necessaryforms and frames for the concrete more economical, simpler and cheaper.

Another object again is to make such a floor construction which will beeasier to build, lighter in weight and cheaper in cost than those usedat present for similar pur-' poses.

Still further objects of this invention will be apparent while thedescription of my in vention proceeds.

For a'full description of the invention and the merits thereof and alsoto acquire a knowledge of the details. of construction of the same foreffecting the various results mentioned hereinbefore, reference is to behad to the following description and accompanying drawings.

While the essential and characteristic features of the invention aresusceptible of modification, still the preferred embodiment ofthe-invention is illustrated in the accompanying drawings, in which Fig.1 is a plan view. of a floor construction made according to myinvention,

Fig. 2 is a vertical sectional view of said floor construction, thesection being taken on the line 2--2 of'Fig. 1,

Fig. 3 is a more detailed plan view of a connecting plate applied to thecolumns of the building to which my reenforced concrete floorconstruction is to be built,

Fig. 7 is a detail view of one of the connecting plates employed in theabove mentioned second modification of my invention, Fig. 8 is adiagrammatic plan view of my invention employed in connection with builtstone or brick columns-,-

Fig. 9 is-a diagrammatic plan view of a portion of the floor constructedaccording to my invention and joined at the corners of the building tobuilt brick or stone walls.

Fig. 10 is a similar View to Fig. 9 showing I said connection at thesides of a wall, and Fig. 11 is a vertical cross sectional View of sucha construction, the sectionbeing taken on the line 1111 of Fig. 10.

Referring more closely to the drawings, 12 indicates the column of thebuilding, in this case it being made of structural steel. At the centerline-of the floor to be constructed, I apply connecting plate 13'andfasten it to the column 12. This. plate is shown on an enlarged scale inFigs. 3 and 4 and is preferably made ofcast -iron. In this case it isshown as of octagonal shapeand around its sides on its upper surface ithas lugs 14 into which are connected the single rods of reenforcingbands 15. Said rods are preferably formed into an end loop 16 thrownover the lugs 14 and secured by'wire. clasps 17. In order to take up thepossible bend and loose.- ness of the rods 18, keys 19 and '20 areemployed into the loop 16 and the rods can be pulled tight by drivingsaid keys against each other. v

In order to construct the concretefioor, I

first employ reenforcing bands 15 in two directions, connecting thecolumns in their lines, and in the diagonals of the squares formed bytheir lines. These bands will be' connected to the plates 13 in themanner ex-' plained hereinbefore. In the diagonal direcadditional' rodsat the. twosides of the onginal bands, distributing them at a largerdistance from each other than the rods of the original bands are placed.Said additional diagonal band rods are shown in Fig. 1 marked 21. andthey are bound into a'rectangular or square stiffening and reinforcingrod shape 22 placed around each column. Further additional reinforcingrods 23 and 24 may be employed at still larger distances-from each otherin the two diagonal directions at the two sides of the and properlyfastened and also secured to each other, the concrete may be poured andthe floor isready.

In case a temporary steel beam construction is needed, horizontallyconnecting, reinforcing and stifiening the columns of the building whilethe erection work is going on,

the construction shown on Figs. 5 to 7 may be employed. In thismodification 12 again represents the structural steel columns of abuilding. Between said columns a system of horizontal stiffening beams2525 are applied, which are useful only while the erection is going onand which may-be lighter and lower than the beams usually employed ifthey have to carry the load of the floor.

' Specially shaped cast iron quarter plates 26 are in this case employedin the four corners formed by the reinforcing beams 25 and fastened tothe columns in the center line of the floor by their extensions 27.These quarter plates are similarly constructed to the plates 13described above and the load carrying and reinforcingbands are securedto them in the same way asthey have been secured to the plates 13 in theconstruction detailed hereinbefore. Load bands 15 and additional rods 21are employed in a similar manner as mentioned above, only the stiffeningrectangular shapes 22 are replaced here by sin gle sides- 28., The fieldreinforcements for the floor run in this case in the directions of thecolumns and not in their diagonals and 4 are represented by the rods 29and 30.

My system of reenforced concrete floor construction may also be appliedto buildings with stone or brick columns and walls. Figs. 8 to 11 showsome details of such constructions. In Fig. 8 the numeral 31 representsthe outlines of a brick or stone column, 32 indicates the octagonalconnecting plate built into the column in the center line of the floor.The construction of these connecting plates and the method of securingthe rods to them is entirely similarto those described above. A centerrod 33 is built into the column and through a suitable hole in thecenter of the connecting. plate to further secure said plate in thecolumn, and will be described presently..

At the corners of the building-the rein forcing rods are connected toquarter platesshownon Fig." 9 and said quarteP-plates are secured intothe corners of the walls byextensions 34 and 35 which may befurthersecured into the walls by the vertical rods in this-case three ofthem being shown. 1 Figs. 10 and llshow the construction used andhorizontal so that v as the boards need not afterwards be re easeshaving stone or brlck walls. Here again a specially formed connectingplate 36 is used. similar to thoseused hereinbefore and con nected tothe wall by extensions 37 and 38 through which pass the vertical rods33. Said rods are built into the wall or column of the building andserve to further secure the connecting plates or their extensions to thecolumn or to the wall of the building.

As will be seen, my floor construction does not need any horizontalbeams to carry the load and transfer it to the columns or walls of thebuilding. All the loads on the floor will be directly transferred bythis system of reinforcement to the columns or the walls.

Another advantage of my system against other floor constructions as usedat present is that the upper and lower surfaces of the floor areabsolutely parallel to each other the building of the the concrete isgreatly facilitated be-cut to any special forms for shapes.

As the horizontal load beams are eliminated, the costs of erection aregreatly reduced, at the same time the floor will be much lighter thanheretofore and the columns also can be built cheaper and lighter thanwith the present systems.

The reinforcing rods everywhere in the floor form such a reinforcingtriangde that any load at any point of the floor will always bedistributed on all the four columns limiting the field in question. Allthe rods of the reinforcing system are stressed for tension only.

The columns of the building may be distributed in number.

any suitable system, form and This system of reenforced concrete floorcan be used with stone or brick buildings as wall as with concretebuildings. My floor construction at. the same time is absolutely fireand water proof.

In case temporary horizontal beams are used while theerection work isbeing done, said beams do not carry any load afterwards, can be of lightand low dimensionsand can crete.
